Update Information
Hey everyone!

Today's patch contains fixes for some common crashes that have cropped up, as well as fixing new seed delivery strangeness related to mutants.

Take care!

Changes

 * Sublimation Station emission cell moved one space down to make it consistent with the Oxygen Diffuser and to prevent emissions from destroying solid cells above

Fixes

 * Worldgen: Fixed an issue preventing some POIs from being selected.
 * Fix crash when two different mutations of Sleet Wheat or Nosh Bean land in the same spot
 * Fix a case where plant mutations weren't being copied between seeds correctly. This was leading to weird behaviour and crashes in various places. Fixes duplicants dropping seeds when taking from a stack in a locker
 * Prevent Duplicants from fetching multiple seeds of different mutant types. Fixes seeds being dropped if they were in a locker next to each other
 * Fixed crash unpacking Interplanetary Payloads during or after landing
